FREEMAN M. TEEGUARDEN, OF COLFAX, INDIANA, ASSIGNOR TO THE SAFETY CORN HUSKER AND SHREDDER COMPANY, OF INDIANAPOLIS, INDIANA.

CORN-HUSKER AND FODDER-SHREDDER.

SIEEGIFICATION forming part of Letters Patent No. 577,466, dated February 23, 1897.

' Application filed April 7, 1896. Serial No. 586,536. (No model.)

To all whom it may concern.-

Be it known that I, FREEMAN M. TEEGUAR- DEN, a citizen of the United States, residing at Colfax, in the county of Clinton and State of Indiana, have invented certain new and useful Improvements in Corn-Huskers and Fodder-Shredders, of which the following is a specification.

Referring to the accompanying drawings, which are made a part hereof and on which similar figures and letters of reference indicate similar parts, Figure 1 is a perspective View of a machine embodying my said invention as seen from one side thereof, the corndelivering carrierbeing removed so that other mechanism will not be hidden thereby, while the feeding and fodder-delivering carriers are extended in position for use; Fig. 2, a similar elevation of the opposite side of the machine, the foldable sections of the feeding and fodder-delivering carriers being folded up in position for storage or transportation, while the corn-deliverin g carrier is in the position it occupies in use; Fig. 3, a central sectional view of the principal portions of said machine, on an enlarged scale; Fig. 4, a detail view, on a still further enlarged scale, illustrating the snapping-rolls5 Fig. 5, a detail sectional view on the dotted line 5 5 in Fig. 4; Fig. 6, a detail sectional view on the dotted line 6 6 Fig. 7, a detail elevation as seen from the dotted line 7 7 in Fig; 3 Fig. 8,'a detail sectional plan View as seen from the dotted line 8 Sin Fig. 3, and Fig. 9 a detail cross-sectional view of one pair of the rolls shown in Fig. 8.

The corn as it comes from the shock is placed on the carrier-belt 1 and is carried thereby and by the overhead carrier-belt 2 to a point adjacent to the snapping-rolls 3 and 4, between which the stalks of corn pass, while the ears are snapped off or severed therefrom and fall down onto the husking-rolls 5. The stalks or fodder being carried between the rolls 3 and 4 comes in contact with the cutters 6 and cylinders 7 and is thereby and by the cutters 8 on the concave thoroughly cut up and reduced to condition for use. It then falls onto the carrier-belt 9, which delivers it to the second carrier 10, by which it is carried out of the machine into a mow or stack, as may be desired. The cars of corn when they fall onto the rolls 5 travel down the same toward the lower end thereof, and during their passage are stripped of their husks by said 5 5' rolls 5. The construction of the husking-rolls is best shown in Figs. 8 and 9, and each roll is provided with alternate projections a and depressions 1) throughout its length. One roll of each pair is also provided with one or more knives 0t and the other roll of the pair with one or more grooves 2), corresponding to said knives. These knives and grooves are at the extreme upper end of said rolls, just where the corn first falls onto them. As will be readily understood, particularly by an inspection of Fig. 3, the action of the machine is such as to drop the ears of corn onto these rolls 5 point first, the cornstalks being fed in between the carriers 1 2 butt-end first in prop- 7o erly manipulating the machine.

The point of an ear of corn generally has more or less silk extending out therefrom, which is matted or intertwined with the huskpoints which project beyond the ear, thus holding the husks firmly onto the ear. The office of the knives a is to clip off these huskpoints and silk, thus freeing the main body of the husks and allowing them to be torn 01f much more readily. After these points are so clipped off the ears travel on down the rolls, and during the time they are passing over said rolls the projections a and depressions b engage with the loosened husks and strip them off, completing the husking operation by the time the ears reach the lower ends of said rolls, when the husked ears are finally delivered onto the carrier-belt 11 and are by said carrier-belt delivered onto a second carrier-belt 12 of the corn-delivering carrier 13. 0 I

As shown in Fig. 8, these rolls 5 are mounted on shafts 14 and run in pairs toward each other, being all geared together by spur-gears 15, as shown. The boxes 16, in which these shafts are mounted,rest on appropriate frame- 9 5 timbers and are pressed toward each other by springs 17, as clearly shown in Fig. 9. The operation is, therefore, that said rolls will yield somewhat relatively to each other, as re- .quired by the work, so that when a larger 10o bunch of husks or blades than usual is stripped off the rolls will separate and permit them to pass through onto the carrier-belt 9, after which said rolls will immediately come closely together again.

As will be seen, especially by an inspection of Figs. 8 and 3, the shafts 1 1 of the husking-rolls 5 extend on to beyond the corn off-bearing belt 11, passing through between the two sides of said belt, and the gears by which said rolls are driven are on the extreme ends of said shaft beyond said off-bearing belt. The gears 15 all mesh together, and one of the shafts (preferably one of those at or near the center of the group) extends on still farther and carries on its extreme end a sprocket-wheel 27, which is driven from the shaft 23 by a sprocket-chain 28. The advantage of this arrangement of these drivinggears is that thereby they are all beyond the point where the rolls operate to husk the corn and are consequently farther removed from the influence thereof. It has been common to put the gears at the other ends of the rolls close to where the corn is delivered thereonto and where the variation relatively to each other of said rolls is greatest. By my arrangement I not only remove the gears from this point, but also put them beyond the corn offbearing carrier-belt, where they are substantially wholly unaffected by the variations described.

The machine is driven by a belt running from some suitable source of power (not shown) to a pulley 18 on the end of the shaft of the cylinder '7.

The overhead carrier-belt 2 is driven from a roll 10 and runs over an idle-roll 20, the latter of which rests on the upper edge of the frame of the carrier-belt 1, so that said two carrier-belts while running close together do not come in actual contact with each other, and so that said carrier-belt 2 may rise to any extent desired, pivoting in so doing upon the shaft of its roll 19. The frame in which the carrier-belt 1 is mounted is made in two sections, joined together at 21, and it is adapted to be folded up in arranging the machine for storage or transportation, as shown in Fig. 2. The frame in which the carrier-belt 10 is mounted is also jointed at 22 and is adapted to be folded up under similar circumstances, as also shown in Fig. 2.

The corn-delivering carrier 13 is adapted to be separated entirely from the machine, if desired, being preferably provided with attaching-hooks at its lower end which will engage with the shaft 23. While this corndelivering carrier is removed in Fig. 1, that portion of the shaft which receives it is there shown, and the method of attachment will thus be readily understood.

The snapping-rolls 3 and at are preferably composed of numerous short grooved sections placed end to end on suitable shafts which carry them. The grooves are preferably spiral in form, and these sections are placed on the shafts provided therefor, part with the corresponding ends in one direction and part with the corresponding ends in the other direction, so that the spirals lead from the ends toward the centers, where they meet, as shown in Fig. 4c. The tendency of the rolls with this formation is rather to draw the corn in from the sides, and so insure that it shall receive the full operation of the rolls and cutters. As is also shown in said Fig. 4, the shafts of these rolls are mounted in bearings in the adjacent framework, and the upper bearings 24 are yielding and are held toward the lower bearings 25 by the springs 26. The rolls are thus enabled to separate somewhat to permit the stalks of corn to pass, while still being held firmly enough toward each other to sever the. ears of corn therefrom. These rolls are both positively driven, preferably by means of chain belts running onto the sprocket-wheels 28 and 29, respectively, one being driven one from one side of the machine and one from the other, as may be observed by reference to Figs. 1 and 2.

The direction of motion of many of the parts is indicated by arrows placed upon or alongside the parts, respectively.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. In a husking and shredding machine, the combination, of the two feeding carrier-belts, the frame of the upper one being swung loosely on its shaft, the snapping-rolls just at the point of delivery of said belts, an inclined concave with knives just behind said snapping-rolls to receive the fodder, a shreddingroll with knives mounted to revolve just above said concave, and the husking-rolls beneath and in front of said snapping-rolls, and mechanism geared thereto for driving the same beyond the point of delivery for the corn, all substantially as set forth.

2. The combination, in a husking-machine, with the feeding carriers and snapping-rolls, of husking-rolls in the form of plain cylinders having alternate projections and depressions and short knives and corresponding grooves opposite each other at the upper end of each pair, substantially as shown and described.

3. The combination, in a husking-machine, of several pairs of husking-rolls all geared together and running in pairs the shafts whereof project outwardly beyond the ends of the rolls, driving-gears for said rolls on the ends of said shaft, and an off-bearing carrier-belt for the corn traveling at the lower ends of said rolls, between them and their gears, substantially as shown and described.

4. The combination, in a husking-machine, of a series of husking-rolls mounted in loose yielding bearings and provided with a series of gears on the lower ends of the shafts beyond the operative portions of the rolls and the off-bearing belt, all said gears being arranged in a single train, and a driving-belt connected to the end of a centrally-located roll-shaft, substantially as shown and described.

5. The combination, in a husking-machine, with the feeding carriers and snapping-rolls, of husking-rolls running in pairs one roll of each pair being provided with a knife at the upper end, and the opposing roll of the pair being provided with a corresponding groove 10 whereby the husk-points and silk may be clipped off as the points of the ears reach said husking-rolls, substantially as and for the purpose set forth.

In witness whereof I have hereunto set my hand and sea], at Indianapolis, Indiana, this 15 30th day of March, A. D. 1896.
